2012 Map of Lake Mathews

About this map

Lake Mathews serves as the central focal point of this Inland Empire landscape, defined by its massive water storage and engineering infrastructure including the Cajalco Tunnel and Mathews Dike. The surrounding terrain transitions from the residential developments along La Sierra Ave and Vista Del Lago Dr to the more open, high-elevation points of Arington Mountain and Estelle Mountain. South of the reservoir, the map documents a mix of agricultural and recreation-oriented land use, featuring the Gavilan Springs Ranch and the resort-adjacent community of Glen Ivy Hot Springs. Along the western edge, the path of the Temescal Wash cuts through a corridor of industry and old settlements like Arcilla and Temescal. This 2012 survey provides a clear view of the suburban interface with the Gavilan Plateau, where rural properties like the Diamond B Ranch sit near the growing residential fringes of Riverside County.
